Question

Olivia places her pet frog on a line to observe the frog motion. The line is divided into sections that measure 1 centimeter each. the frog begins at 0, moves 18 centimeters forward, moves 6 centimeters backwards, and then 12 centimeters backward. What is the frog's displacement?

Answer 1

There is no displacement. The frog is back where it began.

Answer 2

Answer:

displacement of frog is zero

Explanation:

Displacement of the frog is given as

$d_1$ = 18 cm forward

$d_2$ = 6 cm backwards

$d_3$ = 12 cm backwards

so here we have

$d_1 = 18 cm$

$d_2 = -6 cm$

$d_3 = -12 cm$

so we have

$d = d_1 + d_2 + d_3$

$d = 18 - 6 - 12$

$d = 0$
